Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and in particular to a unit-type multicolor printing press. Background Technology

[0002] The demand for high-variety, small-batch, and short-lead-time strip materials in fast-moving consumer goods (FMCG) packaging, labeling, pharmaceuticals and daily chemicals, tobacco and alcohol, and industrial applications continues to grow. Meanwhile, long-term, high-speed production still accounts for a significant proportion of food, beverage, and export packaging. Printing equipment needs to balance high speed, high registration accuracy, rapid plate / process changeover, low waste, and environmental compliance. Modular multicolor printing presses are particularly advantageous due to their modular structure, scalable processes, and online linkage capabilities.

[0003] The aforementioned existing technical solutions have the following drawbacks: traditional printing presses are limited in their flexibility in multi-process linkage and long-line expansion, and the plate changing path of the whole machine is relatively long. Non-absorbent substrates such as films require additional coating and drying curing, and the conversion between solvent / water-based ink systems is complicated. Utility Model Content

[0004] The purpose of this invention is to provide a unit-type multicolor printing machine to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A multi-color printing press unit includes a first placement frame with multiple conveyor rollers rotatably mounted inside, the axes of which are arranged front and rear. The first placement frame is used to hold the roll material to be printed. A first printing press is fixedly installed on the right side of the first placement frame and is used to print a first color on the roll material. A first dryer is fixedly installed on the right side of the first printing press and is used to quickly cure the printing ink. A second printing press is fixedly installed on the right side of the first dryer and is used to print a second color on the roll material. A second dryer is fixedly installed on the right side of the second printing press and is used to quickly cure the printing ink. A third printing press is fixedly installed on the right side of the second dryer and is used to print a third color on the roll material. A third dryer is fixedly installed on the right side of the third printing press and is used to quickly cure the printing ink.

[0007] By adopting the above technical solutions, printing production efficiency can be significantly improved in multi-color printing processes. Rapid pigment curing means that roll-to-roll materials do not need to wait for extended drying times before proceeding to the next stage, drastically shortening the overall printing cycle for a single roll. In continuous production, this time saving accumulates, effectively increasing equipment output per unit time, improving overall production efficiency and response speed. The setup of multiple dryers enhances the surface properties and durability of printed materials, and the cured pigment film typically exhibits better hardness, abrasion resistance, adhesion, and resistance to water and chemical corrosion.

[0008] In a further embodiment, the first printing press, the second printing press, and the third printing press have the same structure.

[0009] By adopting the above technical solutions, the unified structure means that maintenance personnel only need to master the maintenance skills of one type of equipment, eliminating the need for separate training for different equipment. This significantly reduces training costs and difficulty. Furthermore, it drastically reduces spare parts capital tied up and storage space, improves spare parts turnover efficiency, enables rapid response to equipment failures, and shortens downtime. In terms of production scheduling and personnel management, the unified structure facilitates the simultaneous modification of all equipment at once, reducing the complexity and cost of technology upgrades. It also promotes the rapid dissemination and application of new technologies and processes across the three types of equipment, ensuring an overall improvement in production technology levels.

[0010] In a further embodiment, the first dryer, the second dryer, and the third dryer have the same structure.

[0012] In a further embodiment, the first printing machine includes a first base, a pigment tank, a first printing roller, a first driven roller, a first agitating roller, a first drive motor, a second drive motor, a first cylinder, and a first conveying roller. The first base is fixedly installed on the right side of the first placement frame. The pigment tank is fixedly installed at the top right end of the first base. The first agitating roller is rotatably installed on the top of the pigment tank. The axis of the first agitating roller is arranged front to back. The first drive motor is fixedly installed on the front side of the first agitating roller and rotatably installed with the first agitating roller. The first printing roller is rotatably installed on the front side of the first agitating roller. The axis of the first printing roller is arranged front to back. The second drive motor is fixedly installed on the front side of the first printing roller and rotatably installed with the first printing roller. The first driven roller is rotatably installed on the bottom of the first printing roller. The axis of the first driven roller is arranged front to back. A bracket is rotatably installed on the front side of the first driven roller. The first cylinder is fixedly installed at the bottom of the bracket. The axis of the first cylinder is vertically arranged. The first conveying roller is rotatably installed on the right side of the first printing roller. The axis of the first conveying roller is arranged front to back.

[0013] By adopting the above technical solution, the front-to-back arrangement of the first conveyor roller's axis ensures that the conveying direction is consistent with the direction of the printing material's movement, guaranteeing that the printing material can be smoothly and accurately conveyed to the next process after being printed by the first printing roller. The front-to-back axis arrangement conforms to the conventional path design of material conveying in printing equipment, effectively avoiding problems such as material wrinkling and offset caused by deviations in the conveying direction, thus ensuring the stability of printed product quality. Simultaneously, this arrangement facilitates docking with adjacent equipment to form a continuous production line, improving overall printing efficiency. Furthermore, the front-to-back axis arrangement allows the first conveyor roller to provide more direct support and guidance for the printing material, better cooperating with the first printing roller and the first driven roller to complete material transfer during the printing process, reducing material swaying or displacement during conveying, and further ensuring printing accuracy.

[0014] In a further embodiment, the first dryer includes a second base and a first light box. The second base is fixedly installed on the right side of the first printing machine, and the first light box is fixedly installed on the top of the second base. The axis of the first light box is arranged front and back.

[0015] By adopting the above technical solution, the setting of the light box can quickly achieve the curing of printing pigments, avoiding contamination of the pigments when they enter the next printing unit.

[0016] In a further embodiment, a first winding frame is fixedly installed on the right side of the third dryer, and a plurality of conveying rollers are rotatably installed inside the first winding frame, with the axis of the conveying rollers being vertically arranged.

[0017] By adopting the above technical solution, the vertically arranged conveyor roller has its contact line with the material distributed in the vertical direction during rotation. Compared with the horizontal axis conveyor roller, this can reduce the local pressure on the material surface, reduce the risk of indentation or damage to the material surface, protect the appearance quality of the material, and enable the storage of printed rolls.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The first placement frame and the first winding frame are designed to place and wind up the printing roll material.

[0020] 2. By setting up multiple printing presses, multi-color printing can be achieved in a single process;

[0021] 3. By setting up multiple dryers, the pigments can be cured quickly after each printing process. Attached Figure Description
